Prince William and Kate Middleton left Coronation Concert-goers shocked after they arrived to greet them on The Long Walk. For the surprise walkabout, the Princess of Wales donned a light blue blazer, which she wore over a casual white T-shirt.

She paired these with some casual dark trousers and white trainers, looking worlds away from her regal ensemble at yesterday's Coronation ceremony in Westminster Abbey.

Meanwhile, Prince William sported a dark suit as he shook hands with members of the public. At one point, Kate, picked up a small union flag on a stick which had fallen on the floor and handed it to the well-wisher who dropped it.

Scores of people crowded around the royal couple, with William crouching down to chat to a boy and girl wearing golden crowns.The prince and princess looked relaxed, with William telling one group of well-wishers: “Enjoy the concert tonight”.The surprise appearance took place ahead of tonight's Coronation Concert, which will be kicking off at 8pm and will feature performances by Katy Perry, Take That, and Lionel Richie.
